At Forsmark nuclear power plant a new course called "education in everyday safety" has been started in an attempt to improve the safety culture. The goal is to spread the of expectations and approach the maintenance management has set, to all employees working at the plants. During the course, theory is mixed with practical tasks to reach a common view how work should be done to achieve safety for the plant and the people that work there.The practical tasks are done inside "maintenance simulators". They are built inside 20 ft containers which contains two dummy pipe systems. On the pipe systems some valves, a flow meter and a pump has been installed.

AbstractThe main aim of this study was to investigate if four humour styles, affiliative, self-enhancing, aggressive, and self-defeating humour can be related to all five dimensions of the Big Five Factor Model of personality and study if gender has any influence on those relation-ships. A survey questionnaire was distributed among 72 individuals from Kalmar County, in the South-east of Sweden. There were 42 women and 30 men. A humour test questionnaire, Humour Scale Questionnaire (HSQ), with 32 items was used and the Big Five Factor test with 40 items was used for personality test. The results showed that men have a more aggressive humour than women and that the older we get the less affiliative and self-enhancing humour we have.

Franchise theorists have to a large extent failed to keep up with the actual development in global franchise chains. The recent emergence of fast growing multi-unit-franchisees has fundamentally been ignored, and it has been claimed that the new phenomenon can be regarded as a mere replication of the franchisors? structure and control system into sub hierarchies. This study however, suggests that the reality is more complex. Through conducting case studies of two Nordic multi-unit-franchisees, new theories are built explaining how and why control systems are designed the way they are.

This diploma work covers an investigation over the heat - and hot water systems of thetenant-owner's association, Bogården. The heat - and hot water needs of Bogården aresatisfied by both district heating as well as three heat pumps. Implemented investigationshows that the heat pumps are not used in a profitable way. Apart from that, the reservepossibilities are small. There is also a risk of the growth of Legionella bacterium in thehot water system.Since the heat pumps are already installed, HSB-Gävleborg (responsible for Bogården)has a wish to investigate possible proposed actions for optimization of existing plant.After completed investigation, a new proposed action is presented.

This report has a dual focus. The first goal was to increase the knowledge of how the use of electricity in a residential building is distributed. Electricity in residential buildings is used for lighting in common areas, elevators, pumps and many other appliances. The electricity used for these different parts is to a great extent unknown. A few studies have been carried out and the result of these is referred to in this report.By means of measurements and approximations the use of electricity for various appliances became known.

The main purpose of this study is to investigate the needs of pre-commercial thinning on private owned forest properties, which is considered to be increasing. The reason is believed to be the high cost of labor that pre-commercial thinning brings. Furthermore thinning is costly, the revenue created through pre-commercial thinning are post-poned until the first thinning. The study was made through a survey among members of Mellanskog forest owners association. The survey was distributed by e-mail. The time to answer was set to two weeks. The answers indicate that the most common reason why the pre-commercial thinning is delayed, or not done at all, is the forest owner?s lack of time.

Digital video är ett område som expanderat kraftigt senaste åren. På grund av avancerade videokompressionsmetoder kan numera en hel långfilm rymmas på mobiltelefonen eller den handhållna videospelaren. Men hur fungerar videokompression och hur hårt kan man komprimera en viss filmsekvens med bibehållen användarnytta? I denna uppsats görs en genomgång för grunderna inom videokompression. Dess förhållande till användarnyttan undersöks genom ett experiment.

Many professions, such as doctors and psychologists, have a long history of work practice which have resulted that these professions have created their own ethical guidelines. The IT profession, which can be viewed as a relative young and somewhat immature profession, have yet to accommodate any clear guidelines regarding ethics. It?s therefore imperative to create discussions regarding ethical actions to raise the ethical awareness and also create ethical guidelines. The development of the IT profession is moving forward at a quick pace and it?s important to understand that this rapid advancement is not only changing the profession but also changing the society and the environment.

Stump wood is a hot alternative when the heating plants demands more and more forest fuel. The aim with the study has bean to calculate the costs in four different systems for transportations of stump wood, examine if there are any differences in fuel quality for the stump wood in the different systems, analyse if the fuel quality in stump wood is affected with the time it lays by the road side and how much space the stump wood demands on the road side. To calculate the costs for the different systems a system analysis was carried out, where some of the costs were collected through field studies on Holmen Skog stump experiment and other costs were collected from literature and contacts. Data for the fuel quality study was collected from Eons heat plant in Norrköping. Data for the study of how much space stump wood takes along a roadside was collected from field studies.

The concept of IT has developed into ICT (Information- and Communication Technology) over the years. ICT has an increasing impact in society and the Swedish curriculum (Lpo 94) highlights the importance of school to convey lasting knowledge that constitutes the general frame of reference that everyone in society is in need of. The purpose of this study was to find out how teachers perceive and use ICT in secondary school and discover the teachers? vision concerning ICT.The used approach for the study is a qualitative research with a basis of interviews. Four interviews are made with teachers from the early years of secondary school, at two different schools.

TitleSystems, Stability and Power. The Discourse of Information in Organizing Knowledge.AbstractThe aim of this Master's thesis is to inquire into the consequences of an unequal distribution of power between information discourses in the field of knowledge organisation. A deconstruction of Jennifer Rowley's and John Farrows introductory textbook Organizing Knowledge from 2000 is related to the major discourses of information in LIS. Questions posed in this study are: What meaning is ascribed to information in the material studied? Which information discourses are given a dominant position? Which are excluded? and: How does this affect the construction of the library and information science student's identity, in relation to practices of knowledge organisation? The theoretical framework is provided by Ernesto Laclau's and Chantal Mouffe's theory of discourse and combined with techniques for text analysis originating from the work of Norman Fairclough.The analysis reveals a strong domination of a cognitive discourse of information that underlines the importance of information systems for the organisation of knowledge.

Traditionally the content of fiction has not been described, analyzed, classified and/or indexed to the same extent as non-fiction. As a consequence, this lack of content analysis has resulted in unsatisfactory fiction retrieval in relation to users seeking and search behaviour. This fact is why this Master s thesis is written. The total of library users' seeking and search behaviour is investigated in order to suggest methods to improve user adapted fiction retrieval tools. Suggesting relevant fiction retrieval tools corresponding to users' seeking/search behaviour is another aim of the study.

The purpose with this work was to investigate some alternatives for an effective handling with grain, to find the most economic alternative. It is not common that moisture content is below 14% when harvesting grain in Sweden. To store the grain safe it has to be preserved in some way. I have described some of the most common systems for preserving grain in this paper. I have used the systems as a basis when I made calculations in handling the grain for a company. I have chosen a company placed in south of Sweden. The productions are crop farming and pork.

Soundclash is a phenomenon where groups within the culture of reggae music ?battle? against each other, through strategies including both music and rhetoric. The social interaction in the clash exemplifies the scene hierarchy, in which the participants aim to position themselves as number one. This study includes empirical material from a competition within the Swedish scene, also distributed digitally via Internet sites. The analysis is based on discursive psychology, focusing on rhetoric and the construction of meaning.
